The BA-1 Paging Adaptor enables you to use
master stations of your Aiphone intercom system to page external
speakers. You simply connect a BA-1 to a channel of your master, and
whenever you select that channel, you will broadcast to all the paging
speakers on that channel. If you want multiple zones, you will need
multiple BA-1 units and you will need to dedicate a button on the master
for that zone.
The BA-1 does not provide amplification so it must be
used with a paging amplifier that has the appropriate amplification for
the number of speakers you are trying to drive.
There is no talkback, which means a person cannot respond through the
paging system. However, they could go to an intercom station setup on
another channel of the master and respond that way.
